Hey! Thanks for the mention to eev!!! =)

I just realized that there was something missing in eev, and I fixed
that and commited the fix to the git repository... here is a quick
explanation. When eev-mode is active the key sequence `M-h M-h' runs
`find-here-links', that generates a temporary buffer with "links to
here", as explained in:

  http://angg.twu.net/eev-intros/find-here-links-intro.html
  http://angg.twu.net/2020-find-here-links.html

Now, after the fix, typing `M-h M-h' on a grep buffer generates a
temporary buffer whose last lines are something like this:

  (let ((default-directory "~/bigsrc/emacs27/lisp/"))
    (grep "grep --color -niH --null -e 'local variables:' *.el")
    )

this a (3-line) elisp hyperlink that doesn't need eev to run, and that
should make sense to non-eev users... and they should find the
directory part trivial to adapt.

  Cheers, thanks, and apologies for the shameless plug =),
